Brush for applying makeup, a device fitted therewith, and a method of manufacture

Abstract

The invention relates to a brush for applying makeup, in particular mascara, the brush comprising a core made up of two twisted-together lengths of wire between which bristles are held. At least some of said bristles are constituted by bristles of deformable section each having at least two zones of preferential deformation extending along the length thereof.

I claim: 
     
       1. A brush for applying makeup, in particular mascara, the brush comprising a core having two twisted lengths of wire with bristles held therebetween, wherein at least some of said bristles are constituted by bristles of deformable section, each having at least two zones of preferential deformation extending along the length thereof. 
     
     
       2. A brush according to claim 1, wherein the deformable-section bristles are made by extrusion and, in the extrusion configuration, are of a cross-section that is circular in outline. 
     
     
       3. A brush for applying makeup, in particular mascara, the brush comprising a core having two twisted links of wire with bristles held therebetween, wherein at least some of said bristles are constituted by bristles of deformable section, each having at least two zones of preferential deformation extending along the length thereof and wherein the zones of preferential deformation are zones of reduced thickness. 
     
     
       4. A brush for applying makeup, in particular mascara, the brush comprising a core having two twisted links of wire with bristles held therebetween, wherein at least some of said bristles are constituted by bristles of deformable section, each having at least two zones of preferential deformation extending along the length thereof and wherein at least one of the deformable section bristles has at least two portions that are movable relative to a third portion. 
     
     
       5. A brush according to claim 4, wherein at least one of the deformable-section bristles comprises three hinged-together portions, including a middle portion on which two side portions are hinged. 
     
     
       6. A brush according to claim 4, wherein at least one of the deformable-section bristles has two middle portions that are hinged to each other along one side and each of which is hinged along its opposite side to a respective side portion. 
     
     
       7. A brush for applying makeup, in particular mascara, the brush comprising a core having two twisted lengths of wire with bristles held therebetween, wherein at least some of said bristles are constituted by bristles of deformable section, each having at least two zones of preferential deformation extending along the length thereof and wherein the bristles are milled and present forks. 
     
     
       8. A brush for applying makeup, in particular mascara, the brush comprising a core having two twisted links of wire with bristles held therebetween, wherein at least some of said bristles are constituted by bristles of deformable section, each having at least two zones of preferential deformation extending along the length thereof and wherein the zones of preferential deformation are made of a material that is different from the material(s) from which the remainder of the bristle is made. 
     
     
       9. A brush for applying makeup, in particular mascara, the brush comprising a core having two twisted lengths of wire with bristles held therebetween, wherein at least some of said bristles are constituted by bristles of deformable section, each having at least two zones of preferential deformation extending along the length thereof and having recess portions in which makeup can accumulate, said recess portions opening along the length of said bristles of deformable section. 
     
     
       10. Deformable-section bristles each having along its length at least two zones of preferential deformation. 
     
     
       11. Bristles according to claim 10, wherein the bristles are made by extrusion and present in their extrusion configuration a cross-section of circular outline. 
     
     
       12. Deformable-section bristles each having along its length at least two zones of preferential deformation, wherein each of the deformable-section bristles has at least three portions including a middle portion having two side portions hinged thereto. 
     
     
       13. A method of manufacturing a brush comprising a core made up of two twisted-together lengths of wire forming turns between which bristles are held, the method comprising the steps consisting in: extruding shaped strips of plastics material having at least three portions interconnected by zones of preferential deformation;   cutting up said shaped strips to constitute deformable-section bristles;   placing the deformable-section bristles between two lengths of wire, each deformable-section bristle being of arbitrary angular orientation about its own longitudinal axis; and   twisting together the two lengths of wire to form turns between which said bristles are held.   
     
     
       14. A method according to claim 13, further including the step consisting in milling the bristles. 
     
     
       15. A conditioning and applicator device for a makeup, the device comprising a reservoir containing said makeup, a wiper member, and an applicator comprising a stalk provided at one end with an applicator element and at its other end with a handle element also constituting a closure cap for the reservoir, wherein said applicator element is constituted by a brush for applying makeup, in particular mascara, the brush comprising a core having two twisted lengths of wire with bristles held therebetween, wherein at least some of said bristles are constituted by bristles of deformable section, each having at least two zones of preferential deformation extending along the length thereof.
